There are different cases.
If there's a gldisplaywayland in glcontextegl, in this case, we should call
gst_gl_display_egl_from_gl_display to retrieve EGLDisplay.
(This is the case that's using gst-play or totem.)

But if gldisplayegl in glcontextegl, we can use just gst_gl_display_get_handle.
(This is the case that's in WebkitGTK.)
